Light sources can be divided into three ways according to their luminous forms: thermal radiation light source, gas discharge light source and electroluminescent light source. Energy-saving light source is a light source with the characteristics of environmental protection, high brightness, low energy consumption and long life. Led light source is a common light source category in household lighting products, which was invented in 1960s. In the next few decades, its basic use is as an indicator light for electronic equipment such as tape recorders.
This light bulb has the characteristics of high efficiency and long service life, and can be used continuously for 65,438+10,000 hours, which is 100 times longer than ordinary incandescent light bulbs. Scientists predict that in the next five years, this kind of light bulb is likely to become the mainstream of the next generation of lighting.
